Incorrect; Part NCO states:
NCO.IDE.A.160 Hand fire extinguishers
(a) Aeroplanes, except touring motor gliders (TMG), shall be equipped with at least one hand fire extinguisher:
(1) in the flight crew compartment; and
(2) in each passenger compartment that is separate from the flight crew compartment, except if the compartment is readily accessible to the flight crew.
(b) The type and quantity of extinguishing agent for the required fire extinguishers shall be suitable for the type of fire likely to occur in the compartment where the extinguisher is intended to be used and to minimise the hazard of toxic gas concentration in compartments occupied by persons.
